All launch vehicle propulsion systems employed to date have been chemical rockets falling into one of three main categories: Solid-propellant rockets or solid-fuel rockets have a motor that uses solid propellants, typically a mix of powdered fuel and oxidizer held together by a polymer binder and molded into the shape of a hollow cylinder. The ...
By the 1970s, rice burner was a US English slang term for the Vietnamese people during and after the Vietnam War. [16] It was used in the US by "Detroit loyalists" to disparage more economical Japanese competitors of the US car industry during the 1970s energy crisis. [19]

However, mass fraction may have little to do with the costs of a rocket, as the costs of fuel are very small when compared to the costs of the engineering program as a whole. As a result, a cheap rocket with a poor mass fraction may be able to deliver more payload to orbit with a given amount of money than a more complicated, more efficient rocket.
